For public health authorities

Making the decision support system available to citizens and professionals, whether for occasional use via Mentor or through a digital vaccination record, allows:

• To disseminate national or regional vaccine recommendations in a reliable, intelligible, and instantaneous way to everyone.
• To fight against vaccine hesitancy with sourced and reasoned recommendations.

The establishment of vaccination information systems based on the CVN allows for a precise and immediate observability of the actual vaccination coverage, taking into account individual risk factors, as well as the rate of occurrence of adverse events, whether on the scale of:

• a representative sample
• a specific vaccination campaign
• an entire population

Recording in the CVN the individual characteristics used for decision support allows for targeted communication campaigns to people at risk.
